How to Replace Wood Strips in a Fiberglass Garage Door

A garage door is subject to a variety of elements, including wind, rain and sun. While materials such as fiberglass fare very well in these conditions, wood traditionally does not. If you have a fiberglass garage door with wood strips that have seen better days, you can remove and replace the wood without having to replace the entire garage door. This project will take approximately two days to complete, from start to finish.

  • Pry bar
  • New wood strips

    • 1

      Remove the old wood strips with a pry bar. Insert the end of the pry bar underneath the wood and pry outward. Continue until all of the strips have been removed.

    • 2

      Measure the size for the strips with a measuring tape and make a mark with a pencil.

    • 3

      Cut the new wood strips to fit using a circular saw.

    • 4

      Sand the strips with a fine-grit sanding block. This will help prepare the surface for staining or painting.

    • 5

      Stain or paint the wood strips to the desired color. Paint or stain with the grain. If staining, let the coat dry for at least six hours. If painting, wait four to six hours.

    • 6

      Rough up the surface lightly with a sanding block, and seal the wood with polyurethane. This will help protect it from the elements. Use an exterior, non-yellowing, polyurethane and apply it over the strips with a paintbrush.

      Affix the wood strips to the fiberglass door. Use the old glue marks as a guide for placement. Coat the back of each strip with wood adhesive, and firmly press it onto the door. Let this cure for at least 24 hours before using the door.
